You mean like how on a bicycle going up hill you would make a series of snake like curves to ease the load on your legs going up hill, essentially make it feel as if the hill wasn't as steep. Or on roller skates going backwards you do the same thing to gain momentum. I suppose you could, but constantly shifting lanes, or swerving between lanes may make you a target for cops; who think you are drunk and avoiding imaginary cars. Besides wouldn't turning the tires fractionally increase the load on the engine and increase rolling resistance by adding a twisting force to the contact patch?
